Overview
This industrial-grade spiral wound gasket is engineered for high-integrity sealing in critical piping and flange connections. It is manufactured in strict compliance with the ASME B16.20-2007 standard, ensuring dimensional accuracy and performance reliability for pressure vessel and piping applications. Designed for a nominal pipe size of 3 inches with a 300-pound pressure class rating, this gasket is built to handle demanding service conditions involving elevated temperatures, high pressures, and aggressive media. The inclusion of a dedicated inner ring provides superior mechanical stability in the flange assembly.
Key Features
ASME B16.20-2007 compliant construction for guaranteed interchangeability
Robust spiral wound design with alternating metal and filler layers Primary sealing element wound from 316L stainless steel for corrosion resistance
Graphite filler material offers excellent thermal conductivity and resilience Integral 316L stainless steel inner ring prevents gasket winding collapse Inner ring centers the gasket and provides radial support during bolt-up Suitable for high-pressure and high-temperature industrial fluid systems
Individually supplied to prevent damage and maintain seal integrity
